  Schaufel für   Gaz-un    Dampfturbinenl.



   Es ist bisher nicht gelungen, die Schaufeln für   Gasturbineu    aus einem Material herzustellen, das den hohen   Temperatureu cler    Betriebsgase dauernd widerstehen konnte.



  Ebenso sind   der Uberhitznng des Dampfes    bei Dampfturbinen aus dem gleiclien Grunde ziemlich enge   ('renzell    gezogen, da der Stahl höhere   Temperaturen ais die heute maximal    üblichen   nichet      verträgt.   



   Gegenstand der vorliegenden Erfindung ist nun eine Schaufel für   Gasturbinen und Tur-    binen   für hochübcrhitzten Dampf,    welche   min-    destens teilweise aus Quarz besteht. Da Quarz erst bei einer Temperatur von gegen 1700 C schmilzt und gegen   plötzlichen      Temperatur-    weehsel   unempfindlicl ist,    so werden derartige Schaufeln von den   Betriebsgasen der Gas-      turbineo, deren Temperatur    in der Verbrennungskammer etwa 1200"C beträgt und in der Turbine selbst rund 700 C, nicht angegriffen.

   Dasselbe gilt für   hochüberhitzten    Dampf von beispielsweise   500  G, In beiden    Fällen, in Gasturbinen wie in   Turbinez    für   hochüberhitzten    Dampf, kann die vorliegende Schaufel für diejenigen Stufen angewendet werden, deren Temperatur oberhalb der fur Metallschaufeln kritischen Temperatur liegt, während für die Stufen unterhalb dieser kritischen Temperatur wie bisher Metall  schaufeln angewendet werden können.   



   Die Schaufel gemäss vorliegender Erfindung kann ganz aus reines Quarz bestehen. Sie    kann aber auch noch mindestens ein schwer    schmelzbares Metalloxyd. z. B.   Zirkonoxyd,    Titanoxyd, Magnesiumoxyd oder Aluminiumoxyd enthalten. Ferner kann die aus reines   quartz    bestehende Schaufel einen Überzug aus mindestens einem der genannten Oxyde   aufweiseo.

     UNTERANSPRUCHE    :    1. Schaufel nach Patentanspruch, dadurch       gelienuzeichnet,    dass sie ganz aus reinem
Quarz   l) esteht.

  Shovel for Gaz-un steam turbine oil.



   So far it has not been possible to manufacture the blades for gas turbines from a material which could permanently withstand the high temperatures of the operating gases.



  Likewise, the overheating of the steam in steam turbines is rather narrow for the same reason, since the steel cannot withstand higher temperatures than the maximum normal today.



   The subject matter of the present invention is a blade for gas turbines and turbines for highly heated steam, which blade consists at least partially of quartz. Since quartz only melts at a temperature of around 1700 C and is insensitive to sudden changes in temperature, such blades are deprived of the operating gases of the gas turbine, the temperature of which is around 1200 C in the combustion chamber and around 700 C in the turbine itself , not attacked.

   The same applies to highly superheated steam of, for example, 500 G, in both cases, in gas turbines as in Turbinez for highly superheated steam, the present blade can be used for those stages whose temperature is above the critical temperature for metal blades, while for the stages below this critical temperature Temperature as before metal blades can be applied.



   The blade according to the present invention can consist entirely of pure quartz. But it can also contain at least one metal oxide that is difficult to melt. z. B. zirconium oxide, titanium oxide, magnesium oxide or aluminum oxide. Furthermore, the blade made of pure quartz can have a coating of at least one of the oxides mentioned.



   PATENT CLAIM:
Sclaufel for gas and steam turbines, characterized in that it consists at least partially of quartz.



     SUBCLAIMS: 1. Shovel according to claim, characterized in that it is made entirely of pure
Quartz l) exists.



     2. Shovel according to claim, characterized in that it contains at least one hard-to-melt metal oxide.
